Abstract
The utility model relates to a stepless swinging angle regulating device of an oscillating electric fan; in the device, the variation of the length of a crank in an oscillating disc is directly regulated and controlled by a switch wheel (2) and two small chains (4), via two steel ropes (5) which are bended sufficiently, etc.; the two small chains (4) are in different surfaces and directions, and are basically and correspondingly hinged with the switch wheel (2). Moreover, a principle that a maximum static friction force which is increased by the device, acted on a pin (16) for connecting a rod and owned by a steel cable of the two steel ropes (5) in an external bushing is bigger than the counterforce of a force required by a connecting rod (17) for the swing of a fan head of an electric fan is used, so that a crank (15) can freely stay on the length corresponding to a swing angle of the switch wheel (2) to cause the electric fan to obtain the corresponding swing angle via a four connecting rod mechanism. Therefore, the stepless regulation of the swing angle of the oscillating electric fan is realized.
Description
The utility model is the invention about the stepless regulator of angle in a kind of electric fan of shaking the head.This device fan head be equipped with an energy with a fan all-in-one-piece sleeve in the yaw dish that rotates, its lower end surface is provided with a connecting rod pin prejudicially, this pin with the fan bottom quadratic crank mechanism in connecting rod be connected, the rotation of yaw dish and the plane of movement of quadratic crank mechanism and fan head axis heart line parallel, the tooth bar that the coaxial disjunctor gearwheel of yaw dish is same to be had in the reducing gear of clutch is meshed, clutch is controlled by control mechanism, and control switch is installed in the control panel.
The pivot angle of known oscillating fan is constant, generally is the air-supply of shaking the head in 90 these tilt fixings of degree.This in the use, particularly heat sky, personnel assemble when needing electric fan to make the small angle pivot angle, especially inconvenience just seems.For this reason, the inventor has proposed all improvement projects.Singly be documented on the patent documentation, just have much, it all is the length of managing to regulate a certain bar in the quadratic crank mechanism, to change the pivot angle of oscillating fan.Study carefully its concrete grammar, through conclusion, can be divided into two classes: wherein, a class is directly to regulate from the fan head, and these class methods are simple in structure, but it is very inconvenient to regulate use; Another kind of in the control panel adjusted, its main points are with a steel ropes and a spring, required two active forces when long as adjustable lever reciprocally, and the storage power of its medi-spring is by means of steel ropes.In other words, the suffered pulling force of steel ropes is one makes a concerted effort, and this power makes steel ropes be in tension all the time.So, switch sections can only be provided with a friction constant force system, and perhaps similar swing angle fixed mechanism is in case steel ropes is replied because of the elastic force effect.Like this, the structure of switch sections is just complicated, and has increased the resistance of switching knob.Also have, long with elasticity adjusting lever, reliability stability there is not assurance.In addition, electric fan head is a confined space, and the generally all uncontrollable or clutch mechanism that is unable to hold of these class methods is so can only cast out it.Like this, when not needing electric fan to shake the head, relevant parts are still being done unnecessary friction." a kind of electric fan stepless angle adjusting device " (application number 85203402) of Patent Office of the People's Republic of China's bulletin on July 16th, 86 is an example wherein.Other has " double pendulum angle electric fan " (application number 86208166) example of Patent Office of the People's Republic of China's bulletin on July 1st, 87, it is controlled with two steel ropes, but its essence, be exactly in the oscillating fan, the stack of public slide board type swinging mechaism, but former mechanism reliability is poor, now seldom use, and the side of bulletin decides on a verdict and also do not see improvement.
The purpose of this utility model provides a kind of stepless regulator of angle for oscillating electric fan, it is except the repertoire with known clutch-type head-shaking device, when needed, can also make the pivot angle of electric fan in the 20-90 degree, make step-less adjustment, and significant progress be arranged compared with above-mentioned all class schemes.
Its solution is: with first section described known fan head-shaking device of this specification is matrix, improve wherein yaw dish and control mechanism, specifically: described control mechanism comprises with two enough crooked, and each at least one end has the steel ropes of a gimmal, being connected in one is installed in the switch wheel that can back and forth rotate in the control panel and one and is installed in the back and forth swing angle spare of turn of fan head, wherein, two gimmals are that antarafacial is incorgruous and link substantially accordingly on switch wheel respectively; Described control mechanism also comprise one with the horizontal tooth bar of swing angle spare almost coaxial one, the outer tooth bar of the dish that is engaged in horizontal tooth bar, and shift fork that is fixed on the outer tooth bar of dish; Described yaw dish is the assemblying body of a rotation, outside it, a gearwheel and a supporting plate that meshes with the tooth bar is housed; In it, one group of tooth bar that is engaged in same small gear is housed, wherein two horizontal tooth bars are positioned at the both sides of a longitudinal rack, and with the crank disjunctor, a connecting rod pin that links to each other with connecting rod is erected in the crank bottom, described longitudinal rack upper end, be rotatably connected with above-mentioned shift fork by its axle collar, reach part, the crank of middle trough of belt and supporting plate when axial motion is done in its lower end, and the connecting rod that is stage shape, slot milling in compensation.
Like this, as regulating the electric fan pivot angle, can be earlier by the flexible swing angle driving mechanism in the utility model device, promptly only need the left rotation and right rotation switch wheel, through above-mentioned parts, and the effect that is necessary the parts that add in the specific embodiment, swing angle spare is also done corresponding rotation pari passu.Then, the effect of parts in driving component and yaw dish more finally changes the reciprocal displacement of crank length change into.Again because two enough the bending steel ropes in wire rope, in outer sleeve, had, through apparatus of the present invention increase and by the existing maximum static friction force of link pin daughter, greater than reaction force by the required power of connecting rod swing electric fan, so when switch wheel optionally goes to a certain angle and after removing external force (as the turn power of hand), crank just rests on the corresponding length, and through the effect of quadratic crank mechanism, electric fan can obtain corresponding pivot angle.Utilize above-mentioned principle, just can be indiscriminately ad. as one wishes the pivot angle of oscillating fan be carried out step-less adjustment.
Because device of the present utility model has adopted the direct adjusting control mode of non-spring structure, so two steel ropes generally are in relaxed state, thereby also simplified the structure of switch sections, and reduced the resistance of switching knob, the more important thing is easy to adjust reliable and stable, the effect that can obtain to achieve many things at one stroke.
The another layer design of device of the present utility model is to have kept clutch mechanism, when crank length is maximum, presses sufficient skid plate by plectrum in the driving component, makes clutch separation and keeps a segment distance.Obviously, when electric fan did not need to shake the head, the unnecessary friction of relevant parts had not also existed.So far, the utility model purpose all reaches.
